Description

The State of Delaware is seeking bids for the complete removal and replacement of the low‑slope roof on the Carvel Building at the Herman M. Holloway Campus (approximately 36,800 sq ft). The scope includes demolition of the existing roof system, installation of a new Thermoplastic Polyolefin (TPO) membrane roofing system with insulation, vapor retarder, cover boards, metal coping, roof hatches with guardrails, and optional lightning‑protection system. Bidders must comply with Delaware prevailing‑wage requirements, submit a 10 % bid bond, and be ready to post 100 % performance and payment bonds after award. Key requirements also cover waste‑diversion (minimum 75 % landfill diversion), safety plans, and a two‑year warranty on workmanship. • Replace ~36,800 sf of low‑slope roofing with TPO membrane system. • Provide full metal coping, roof hatches, and optional lightning‑protection alternate. • Mandatory pre‑bid meeting on June 29 2026; electronic bid submission via Bonfire portal by July 15 2026. • Must meet Delaware prevailing‑wage rates, submit bid security, performance/payment bonds, and adhere to waste‑management and safety requirements.

Budget estimate

$1,000,000 – $2,000,000

Based on the roof area (≈ 36,800 sf) and typical commercial low‑slope roofing costs ranging from $30 to $50 per square foot, the total contract value is likely between $1.1 million and $1.8 million. Adding allowances for metal coping, roof hatches, and the optional lightning‑protection alternate pushes the upper bound toward $2 million. Therefore, a reasonable budget range is $1 M–$2 M, recognizing that final pricing will depend on material selections, subcontractor bids, and any change‑order allowances.
